The coating film frame conforms to GB / T16777-2008 and GB / T19250-2003 standards. This coating film frame is a series of tests for tensile properties of building waterproofing materials (polyurethanes, polyacrylates), and a coating film mold for preparing samples. . Using this coating film mold, a sample film of 350mm320mm * 1.5mm can be made, and then the coating film can be cut with a microtome to obtain a dumbbell-shaped type I sample that meets the requirements of the GB / T528 standard for different tensile tests.
Coating film frame technical parameters:
★ Structure: The coating film mold consists of a mold frame, a coating bar, a substrate and a base.
★ Dimensions: 410mm * 380mm * 1.5mm
★ Inner frame size 350mm * 320mm * 1.5mm
★ Coating film thickness (1.50.2) mm:
How to use the coating mold frame:
★ Before the preparation of the samples, the samples taken and the instruments used were placed under standard conditions (temperature 23 ° C ± 2 ° C; relative humidity 45% ~ 70%) for 24 hours.
★ In order to facilitate demolding, silicone oil or paraffin can be used as a mold release agent on the substrate (glass plate) and mold frame for surface treatment.
★ Under standard conditions, stir the sample after standing evenly. If the sample is a two-component coating, weigh the required main agent and curing agent according to the product mix ratio, and mix the two components for 5 minutes.
★ Pour the stirred waterproof paint into this coating film mold for coating immediately without mixing air bubbles.
★ The sample should be coated in several steps. After A, the surface should be scraped flat with a coating bar and cured under standard conditions for 168h.
★ Check the appearance of the coating film. The surface should be free of obvious bubbles, smooth and flat.
★ After filming, use a microtome to cut the coating film to obtain dumbbell-shaped type I specimens that meet the requirements of GB / T 528 for different tensile tests.
